research overview

Research is centered on methods to test patients with bleeding or clotting disorders and the types of blood products and role of blood transfusion in treating these conditions.

research statement

Research interests have centered on disorders of hemostasis, especially platelets, - their detection, quantitation and management. Related to this, methods to characterize and improve platelets and plasma blood components. More recently, research on best transfusion practices and patient blood management with an emphasis on transfusion avoidance.
